You should never assume register_global_variablesis turned on. Even if it is, it's deprecated and you should never use it that way.
您永远不应该假设register_global_variables已打开。即使是这样，它也已被弃用，您永远不应该那样使用它。
Refer directly to the $_POSTor $_GETvariables. Most likely your form is POSTing, so you'd want your code to look something along the lines of this:
直接参考$_POST或$_GET变量。很可能您的表单正在发布，因此您希望您的代码看起来像这样：
<input type="hidden" name="date" id="hiddenField" value="<?php echo $_POST['date'] ?>" />
If this doesn't work for you right away, print out the $_POSTor $_GETvariable on the page that would have the hidden form field and determine exactly what you want and refer to it.
如果这对您不起作用，请在页面上打印出包含隐藏表单字段的$_POSTor$_GET变量，并准确确定您想要什么并引用它。
echo "<pre>";
print_r($_POST);
echo "</pre>";

Maybe a little late to the party but why don't you use sessions to store your data?
也许聚会有点晚了，但为什么不使用会话来存储数据呢？
bookingfacilities.php
预订设施.php
session_start();
$_SESSION['form_date'] = $date;
successfulbooking.php
成功预订.php
session_start();
$date = $_SESSION['form_date'];
Nobody will see this.
没有人会看到这一点。

You have to use $_POST['date']instead of $dateif it's coming from a POST request ($_GET if it's a GET request).
如果它来自 POST 请求（如果是 GET 请求，则为 $_GET），您必须使用它来$_POST['date']代替$date。

I'm not sure what you just did there, but from what I can tell this is what you're asking for:
我不确定你刚刚在那里做了什么，但据我所知，这就是你的要求：
bookingfacilities.php
预订设施.php
<form action="successfulbooking.php" method="post">
<input type="hidden" name="date" value="<?php echo $date; ?>">
<input type="submit" value="Submit Form">
</form>
successfulbooking.php
成功预订.php
<?php
$date = $_POST['date'];
// add code here
?>
Not sure what you want to do with that third page(booking_now.php) too.
不确定你想用第三页（booking_now.php）做什么。
